MyExperiment.org is a social networking site and marketplace aimed at scientists who use workflows and services for their research. It allows users to publish, discover, share, and reuse experimental artifacts like workflows. The site aims to make these tools easy to use with a familiar social media-style interface. Key goals include crossing boundaries between individual experiments, disciplines, and systems to facilitate collaboration and intellectual fusion. Challenges include addressing issues around user incentives, metadata, provenance, intellectual property, and quality control as experiments are shared in an open yet curated environment.
